使用下面命令，获取实时日志最后50行：
docker-compose logs -f -t --tail=50
再次刷新功能，看下日志有没有错误记录！
另外，可以参看这篇文章，https://www.zerocode.net.cn/thread/57

看起来像是服务没有连接到nacos，导致获取不到数据库配置

from erd-online.

检查下mysql、nacos是否正常。http://192.168.144.16:8848/nacos，可以访问你本地的nacos。

进入docker容器后什么命令都不识别，如何查看? 刚接触docker

[root@k1 docker]# docker exec -it erd-nacos sh

ip addr

sh: 3: ip: not found

ps

sh: 4: ps: not found

yum

sh: 6: yum: not found

不用进docker排查，在外面用docker-compose命令基本上就可以排查出问题了

from erd-online.

mysql远程都可以连接，不知道nacos容器在哪里，就是好多连接不上nacos异常。哎。
你这模块nacos镜像和nacos有什么关系吗？没有看出来。

搭了好几遍 ，都是这个问题 502 nacos 问题

需要更多的日志信息，才能帮助你排查问题

from erd-online.

可以按照以下顺序，逐步定位：
1、只启动erd-mysql：docker-compose up erd-mysql
2、只启动erd-mysql、erd-nacos：docker-compose up erd-mysql erd-nacos
3、只启动erd-mysql、erd-nacos、erd-auth：docker-compose up erd-mysql erd-nacos erd-auth

单独启动mysql报这个错误

1、应该是重复创建erd数据库了，解决办法如下，注意命令后面有个点：
docker cp 容器ID:/usr/local/work/1schema.sql .
2、修改1schema.sql ，删除新建erd的重复命令，下面命令应该有两行，删掉一行：
CREATE DATABASE test;
3、将文件重新放回容器：
docker cp 1schema.sql 容器ID:/usr/local/work/1schema.sql

nacos数据库连接需要在URL中加上参数 &serverTimezone=UTC，否则nacos一直报No DataSource set
